Abstract

Background & aims Due to its anatomic connection, the liver is constantly exposed to gut-derived bacterial products or metabolites. Disruption of gut homeostasis is associated with many human diseases. The aim of this study was to determine the role of gut homeostasis in initiation and progression of hepatocellular carcinoma (HCC).Methods Disruption of intestinal homeostasis by penicillin or dextran sulfate sodium (DSS) and its restoration by probiotics were applied in a diethylnitrosamine (DEN) model of rat hepatocarcinogenesis.Results Patients with liver cirrhosis and HCC had significantly increased serum endotoxin levels. Chronic DEN treatment of rats was associated with an imbalance of subpopulations of the gut microflora including a significant suppression of Lactobacillus species, Bifidobacterium species and Enterococcus species as well as intestinal inflammation. Induction of enteric dysbacteriosis or intestinal inflammation by penicillin or DSS, respectively, significantly promoted tumor formation. Administration of probiotics dramatically mitigated enteric dysbacteriosis, ameliorated intestinal inflammation, and most importantly, decreased liver tumor growth and multiplicity. Interestingly, probiotics not only inhibited the translocation of endotoxin, which bears pathogen-associated molecular patterns (PAMPs) but also the activation of damage-associated molecular patterns (DAMPs) such as high-mobility group box 1 (HMGB1). As a result, the production of pro- and anti-inflammatory cytokines was skewed in favor of a reduced tumorigenic inflammation in the liver.Conclusions The data highlights the importance of gut homeostasis in the pathogenesis of HCC. Modulation of the gut microbiota by probiotics may represent a new avenue for therapeutic intervention to treat or prevent HCC development.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • High circulating lipopolysaccharide levels in mice and patients with chronic liver disease and hepatocellular carcinoma demonstrate a leaky gut during multiple stages of chronic liver disease and hepatocarcinogenesis.

    “High circulating LPS levels in mice and patients with CLD as well as in HCC14,24,77,78 demonstrate the presence of a leaky gut during multiple stages of CLD and hepatocarcinogenesis (FIG. 1).”
  • Perturbation of gut eubiosis by penicillin increased hepatocellular carcinoma formation in rats, and this increase could be suppressed by probiotics.

    “As such, perturbation of the gut eubiosis by penicillin increased HCC formation in rats77, which could be suppressed by probiotics77.”
  • In a rat model of DEN-induced hepatocarcinogenesis, VSL#3 mitigated enteric dysbiosis, reduced intestinal inflammation, and decreased liver tumour growth and multiplicity.

    “In a rat model of DEN-induced hepatocarcinogenesis, administration of VSL#3 (containing Streptococcus thermophiles, Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium infantis, Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus delbrueckii subsp. Bulgaricus) mitigated enteric dysbiosis, ameliorated intestinal inflammation and decreased liver tum”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
